To all whom it may concern:

Be it known that we, Gnovns C. l/VOLFE and HENRY K. WOLFE, citizens of the United States, residing at Gheney, in the county of Spokane and State of iiashington, have invented certain new and useful Improvements in Weeders and Cultivators; and we do hereby declare the following to be a full, clear,'and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to weeders and cultivators and has for an object to provide a wheeled carriage carrying a shaft or rod adapted to be moved below the surface of the ground and with means to rotate the rod.

The further object of the invention is to provide a wheeled carriage having a rod vertically adjustable and adapted at times to be forced below the surface of the soil and with means operated from the wheels for rotating the rod at all positions.

With these and other ob ectsin View the invention comprlses certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the drawings-Figure 1 is a view of the improved cultivator and Weeder inside elevation. Fig. 2 is a top plan View of the II implement. Fig. 3 is a detail top plan view I of one of the bearings of the rotatln shaft.

Fig. 4 is a view in side elevation'o one of the bearings as shown in Fig. 3; Fi 5 is a detail, sectional view of the bearln'g' as taken on linei55 of Fig. 4. Fig. 6 is a top plan view of the center bearing'providing space for the sprocket. Fig. 7"1s a View in end elevation of the center bearing shown in Fig. 6. Fig. 8' is a rear view of the center bearing as indicated by arrow 8 of Figs. 6 and 7.

Like characters of reference designate corresponding parts throughout the several views.

The frame 10 is supported by an axle 11 and wheels 12 and controlled in any usual or ordinary manner as by the tongue or pole 13., To the forward part of the frame a plurality of braces '14 are pivoted as at 15. At their lower and rearward ends the braces 1 are provided with hearing blocks or boxes 16 and therein is journaled a shaft or rod 17. Also 'journaled upon the frame is a shaft 18 extending longitudinally thereof Specification of Letters Patent. P t nt d Jan, to,

and provided with arms 19 which are pivotally connected with links 20 which extend down to a pivot bolt 21 carried adjacent the front end of the shoe blocks 16. The shaft 18 is provided with a lever 22 engaging a segment 23 in the usual manner and rigidly connected with the shaft 18 whereby such shaft may be rotated to raise and lower the shoe blocks 16, and the brace rods 14.

Centrally of the frame the shaft 11 carries a spur gear 24 which engages a pinion 25 carried upon a shaft 26 which also carries a sprocket 27. The sprocket 27 carries a chain 28 which passes over a sprocket 29 upon the shaft 17 whereby when the shaft 11 is rotated by an action of the wheels 12 the shaft. 17 is also rotated at a much greater rate of speed by reason of the interposition of the gearing mentioned. I

The sprocket 29 is located in a housing 30 having a bottom 31 which prevents the entry of dirt into such housing, suchhousing being carried by a brace rod 32 and pivoted to the shaft at the front of the frame. The housing 30 is also controlled-by one of the arms 20 carried by the rod 18 and a rightangularly disposed arm'33 also carries an idler sprocket 34 engaging the sprocket chain 28 whereby when the lever 22 has been manipulated to raise the rod 17 the sprocket chain 28 is tightened to maintain such chain in operative condition.

'It will .be apparent that with the parts disposed in such relation as shown at Fig.

1 the shaft 17 will be below the surface of I the soil and when drawn across the field such rod will engage the roots of weeds and draw such weeds under the surface of the soil. Therotation of the shaft will be such as to wind the weeds ofl from the rotating shaft so that it will constantly and autoy matically clear itself, whereby the weeds j will be left upon the surface of the soil and the frame in front of the axle and extending to the rear thereof, a shaft journaled at theextremities of the-arms in parallelism with the axle, means to force the extremities of the arms and shaft below the level of the supportingwheels, and means to rotate the shaft from the axle.

shaft mounted i' ,t np0n the rear of the frame, levers and"links"connecting the last mentioned shaft with the extremities of and to force the arms belowthe level of the supportingwheels, andmeans to drive the first mentioned shaft from the axle.

3. The combination of a'frame, axle and supporting wheels, of arms pivoted to the frame in front of the axle and extending to the rear thereof, a shaft journaled at the rear of the frame, a hand lever for rotating links connecting the lever arms to the rear extremities of the ,first mentioned arms, a

rotating member joil'rnaled at the extremi ,tiefs'oi the first mentioned arms, a syrocket chain conveyingmotion from the axle to the rotating member, and a chain tightener carried by the lever arm and moving with the shaft.

In testimony whereof we aflix our signatures in presencepftwo witnesses.
